Detection of Torque teno sus virus 1 and 2 in tissues from stillborn piglets delivered by sows via natural farrowing

J Vet Sci. 2012 Dec;13(4):425-7. doi: 10.4142/jvs.2012.13.4.425.

Abstract

We detected Torque teno sus virus 1 and 2 (TTSuV1 and TTSuV2) in tissue samples from 18 stillborn piglets using nested polymerase chain reaction. The detection rates of TTSuV1 and TTSuV2 were 78% and 50%, respectively, with 83% of the stillborn piglets positive for TTSuV1 or TTSuV2. TTSuV1 was detected highest in the liver (72%) followed by heart (56%), spleen (38%) and tonsils (38%) while TTSuV2 was detected highest in the tonsils (38%) followed by liver (33%), spleen (25%), and heart (17%). These results indicate that TTSuVs are commonly present but not equally distributed among the tissues of stillborn piglets.
